Sewage Waste Water – Malodours
In 2005, the Public Works Authority in Qatar issued a contract aiming to reduce hydrogen sulphide and other malodorous gas levels throughout a catchment area designated PS30. In addition it required:
- A reduction in the level of sewer slime (biofilms) in the sewage catchment pipe and thus suppress sulphide production.
- Reduce the cost of asset degradation from corrosion.Maintain clean sewage pipelines and wet wells, free from blockages caused by organic deposition of fat, oil and grease.
- Assist in front suppression in the biological oxidation in the Sewage Treatment Plant, Reduce quantities of sewage sludge at the Sewage Treatment Plant and so improve treatability of the effluent.
- Stabilize the pH of the raw sewage.
During the period of the contract, SolEco Organic Concentrate demonstrated a progressive and overall, exceptional change for the better. The Malodours were eliminated, to the relief of both the general public and to the environment.
Dissolved Sulphides Test Result – 6th September 2006 PS30 – 1.7 ppm – reduction of 85%
H2S Gas Test Result PS30 – 24th/25th September 2006 – 30 ppm – reduction of 80%
